hand, the first
atomizing surface and the liquid-absorbing surface 119 are physically
isolated, the heating
element 120 indirectly contacts the atomizing medium in a liquid storing
chamber through the

atomizing medium in the liquid storing chamber, so as to effectively isolate a
heat transferring,
which can avoid the deterioration of the atomizing medium in the liquid
storing chamber
caused by high temperature, and the entire atomizing structure can have high
heating efficiency.
On the other hand, the outer wall 116 is in direct contact with the inner wall
portion 112A, the
guiding portion 112 obtains the atomizing medium through the liquid-absorbing

liquid-absorbing
surface 119 in contact with the atomizing medium, the liquid-absorbing surface
119 is
configured to absorb the atomizing medium into an inside of the guiding
portion 112, and the
atomizing medium is transported to an inside of the atomizing portion 111

111 further has
an inner wall 115, the heating element 120 is integrally formed with the
atomizing portion 111
and is located between the outer wall 116 and the inner wall 115. Further, the
inner wall 115

air channel 192
configured to transport the aerosol generated by the second atomizing surface.
In one of the
embodiments, the heating element 120 may be a spiral heating wire, a mesh
heating wire, and
a sheet heating wire. Alternatively, the heating element 120 is provided with
a wire extending
outside the atomizing portion 111.
[0058] In one of the embodiments, the heating element 120 is embedded in the
atomizing
portion 111. The guiding portion 112 has a cylindrical structure including the
inner wall portion
112A and an outer wall portion 112B. The inner wall portion 112A is connected
to the
atomizing portion 111, the outer wall portion 112B is at least partially in
contact with the
atomizing medium, so that the atomizing medium is transported from the inside
of the guiding
portion 112 to the atomizing portion 111, and atomized by the heating element

surface 119. In one of the embodiments, the guiding portion 112 has a regular
circular tubular
structure. In one of the embodiments, the entire outer surface of the guiding
portion 112 away
from the atomizing portion 111 is configured as the liquid-absorbing surface

exhibits a porous shape at the microscopic level, so as to transport the
atomizing medium inside
8
Date Recue/Date Received 2022-12-15
the atomizing core assembly 110 and the atomizing portion 111. Due to the
characteristics of
the porous structure, the atomizing medium is transported through gravity and
capillary action,
so that the heating element 120 can heat the atomizing medium in the atomizing
portion 111 to
generate the aerosol, which can flow out of the atomizing portion 111 through
the first air
channel 191 and the second air channel 192. Further, a pore diameter of the
porous structure is
arranged of 100 nanometers to 120 nanometers. In one of the embodiments, the
pore diameter
of the porous structure is in a range of 1 micrometer to 100 micrometers. In
another
embodiment, the pore diameter of the porous structure is in a range of 10
microns to 50 microns.
The material of the porous structure is ceramic or glass. In one of the
embodiments, an internal
porosity of the porous structure is arranged of 30% to 90%. In another
embodiment, the internal
porosity of the porous structure is arranged of 50% to 65%. Such
configurations are beneficial
to transport the atomizing medium through the inside of the atomizing portion
111.
[0060] Further, in one of the embodiments, the porosity of the guiding portion
112 is greater
than the porosity of the atomizing portion 111, so that the total amount of
the atomizing medium
in the guiding portion 112 is supplied sufficiently, and the relatively small
porosity of the
atomizing portion 111 can prevent leakage of the atomizing portion 111, which
is beneficial to
guide the atomizing medium into the atomizing portion 111. Further, in one of
the embodiments,
the inside of the guiding portion 112 is provided with different pores to form
a guiding channel,
the liquid-absorbing surface 119 transports the atomizing medium to the
atomizing portion 111
through the guiding channel, so as to accurately and uniformly transport the
atomizing medium
to the atomizing portion 111 and the heating element 120, thereby obtaining
the uniform aerosol.
Such the configuration connects the atomizing portion 111 to the guiding
portion 112, and the
atomizing medium is transported through a liquid guiding portion, that is, the
entire tubular
outer wall of the guiding portion 112, a liquid guiding area is great and the
liquid guiding is
performed in all directions, which can effectively ensure the sufficient
supply of atomizing
medium to the heating element 120, and the atomizing portion 111 includes a
plurality of
atomizing areas inside and outside thereof, the amount of atomization is
large.

the atomizing
portion 111 is provided with an avoiding groove 114, the first air channel 191
is in fluid
communication with the second air channel 192 through the avoiding groove 114.
Further, in
one of the embodiments, as shown in FIG. 2, the atomizing portion 111 has a
top portion 117,
the top portion 117 is configured to cooperate with other components to retain
the fluid
9
Date Recue/Date Received 2022-12-15
communication between the first air channel 191 and the second air channel
192. In one of the
embodiments, as shown in FIG. 2 and FIG. 3, the top portion 117 is provided
with a flowing
area 113, the first air channel 191 is in fluid communication with the second
air channel 192
through the flowing area 113. That is, an upper end surface of the atomizing
portion 111 is
lower than an upper end surface of the guiding portion 112, or a lower end
surface of the
atomizing portion 111 is higher than a lower end surface of the guiding
portion 112, so as to
ensure that the air can pass through two smoke channels at the same time, that
is, the first air
channel 191 and the second air channel 192, and flow out from the two smoke
channels. Such
configuration is beneficial to avoid blocking the first air channel 191 and
the second air channel
192 due to a tightly fitted installation, thereby ensuring that the aerosol
generated by the first
atomizing surface is transported through the first air channel 191, and the
aerosol generated by
the second atomizing surface is transported through the second air channel
192.
[0062] Further, in one of the embodiments, the first air channel 191 and the
second air channel
192 are in communication with two sides of the atomizing core assembly 110,
respectively. In
this embodiment, a side of the atomizing core assembly 110 is provided with an
air inlet end,

with the air inlet
end, respectively. Another side of the atomizing core assembly 110 is provided
with an air
outlet end, and the first air channel 191 and the second air channel 192 are
in communication
with the air outlet end, respectively. Further, in one of the embodiments, the
flowing area 113
is provided on the air outlet end, and the avoiding groove 114 is provided on
the air inlet end.
The configuration of the air inlet end and the air outlet end, that is, the
configuration of the
flowing area 113 and the avoiding groove 114, enables external air to enter
the atomizing area
formed by the inner wall 115 and the outer wall 116 due to the action of the
heating element
120, so as to form an outer-inner-outer gas circulation channel, so that the
aerosol generated by
the heating element 120 heating the atomizing medium can be mixed with the
external air and
then flows out.
[0063] In one embodiment, as shown in FIG. 2 and FIG. 3, the atomizing core
assembly 110
is provided with a limiting step 118 above the atomization portion 111 on the
guiding portion
112. Further, an outline of the limiting step 118 is smaller than an outline
of the guide part 112,
so as to form a mounting position. Further, in one of the embodiments, in the
direction of
gravity, a height of the atomizing portion 111 is less than a height of the
guiding portion 112.
Further, in one of the embodiments, as shown in FIG. 5 and FIG. 8, in the
direction of gravity,
Date Recue/Date Received 2022-12-15
the guiding portion 112 is coplanar with the atomizing portion 111. Such
configuration
facilitates the combined use of gravity and capillary action to transport the
atomizing medium
from the inside of the atomizing core assembly 110.
[0064] In one embodiment, as shown in FIG. 2, in the direction of gravity, the
height of the
atomizing portion 111 is greater than the height of the guiding portion 112
but less than the
height of the limiting step 118. The configuration of the limiting step, on
the one hand, is
beneficial to the sealing connection of a ventilation tube and prevent the
atomizing medium
from entering the first air channel 191 and the second air channel 192, and on
the other hand,
it is beneficial to ensure that ensure that the aerosol in the first channel
191 and the second
channel 192 enters the ventilation tube, so as to avoid being sealed and
abutted to cause
communication failure.
[0065] In one embodiment, at least two first air channels 191 are provided,
and the at least two
first air channels 191 are evenly distributed. In one of the embodiments, the
atomizing portion
111 has a central axis, and the at least two first air channels 191 are evenly

wall portion
112A are tangent. Further, in one of the embodiments, as shown in FIG. 3 and
FIG. 4, the outer
wall 116 and the inner wall portion 112A are arranged in contact with each
other through the
protruding structure.
[0067] In one of the embodiments, as shown in FIG. 5 and FIG. 6, a shortest
distance from the
inner wall 115 to the outer wall portion 112B is less than or equal to the sum
of a distance from
inner wall 115 to outer wall 116 and a distance from inner wall portion 112A
to outer wall
portion 112B. When the thickness of the atomizing portion 111 is constant, the
distance from
the inner wall 115 to the outer wall 116 is equal to the thickness of the
atomizing portion 111,
11
Date Recue/Date Received 2022-12-15
which can be defined a first thickness. When the thickness of each portion of
the guiding
portion 112 is the same, the distance from the inner wall portion 112A to the
outer wall portion
112B is equal to the thickness of the guiding portion 112, which can be
defined the second
thickness. The shortest distance from the inner wall 115 to the outer wall
portion 112B is less
than or equal to the sum of the first thickness and the second thickness. For
the embodiment in
which the outer wall 116 is in surface contact with the inner wall portion
112A and the contact
surface is tangent, as shown in FIG. 10, the shortest distance from the inner
wall 115 to the
outer wall portion 112B is equal to the sum of the first thickness and the
second thicknesses.
For the embodiment where the outer wall 116 is in surface contact with the
outer wall portion
112B, and the contact surface is tangent and the outer wall 116 and the outer
wall portion 112B
are tangent, as shown in FIG. 6 and FIG. 7, the shortest distance from the
inner wall 115 to the
outer wall portion 112B is equal to the first thickness and also equal to the
second thickness.
In this embodiment, the first thickness is equal to the second thickness. That
is, the shortest
distance from the inner wall 115 to the outer wall portion 112B is less than
the sum of the first
thickness and the second thickness. Other embodiments are similar to the above
description,
and will not be repeated. Such the configuration, on the one hand, is
beneficial to increase the
contact area between the outer wall and the inner wall portion, on the other
hand, it is beneficial
to improve the transfer efficiency of the atomizing medium from the guiding
portion to the
atomizing portion, the liquid guiding area is great and the liquid guiding is
performed in all
directions, which can effectively ensure sufficient liquid supply to obtain a
large amount of
atomization, which solves the problem of poor atomization effect and
insufficient smoke
volume of conventional atomization.
[0068] Further, at a connecting position of the atomizing portion 111 and the
guiding portion
112, the outer surface of the atomizing portion 111 is tangent to the inner
surface of the guiding
portion 112 or is located between the inner wall portion 112A and the outer
wall portion 112B,
and the distance from the heating element 120 to the outer wall portion 112B
is greater than
the distance from the inner wall portion 112A to the outer wall portion 112B,
so as to ensure
that the heating element 120 maintains a distance from the atomizing medium in
the liquid
storing chamber. Such configuration enables the heating element 120 to be
heated evenly, so
as to ensure the uniformity of the heating of the atomizing medium, and ensure
the consistency
of the atomized aerosol. In addition, the heating element 120 can indirectly
contact the
atomizing medium in the liquid storing chamber to effectively isolate the heat
transfer, which
12
Date Recue/Date Received 2022-12-15
is beneficial to avoid the deterioration of the atomizing medium in the liquid
storing chamber
caused by high temperature.
[0069] In order to prevent the atomizing medium from leaking out, in one of

materials to
prevent the atomizing medium stored in the atomizing portion 111 and/or the
guiding portion
112 from leaking out of the atomizing core assembly 110. Further, in one of
the embodiments,
the leak-proof sealing layer is located on the position of the guiding portion
112 except the
liquid-absorbing surface 119 and the position contacting the atomizing portion
111, so as to
prevent the atomizing medium from leaking.

[0074] Further, in one of the embodiments, as shown in FIG. 14 and FIG. 15,
the atomizer
further includes the middle sealing element 130. The middle sealing element
130 is provided
with a lower end cavity configured to accommodate the atomizing core assembly
110 or the
atomizing portion 111, such as, the flowing area 113. Alternatively, the

step 118, so
as to facilitate assembly and sealing, and prevent the atomizing medium from
entering into the
first air channel 191 and the second air channel 192. In one of embodiments,
the atomizer or
the atomizing structure 100 further includes the ventilation tube 150, the
ventilation tube 150
is inserted into an upper cavity provided on the middle sealing element 210,
the upper cavity

[0075] In one of the embodiments, as shown in FIG. 14 and FIG. 15, the
atomizing structure
100 further includes a mounting element 160 and a sealing sleeve 170. The
guiding portion 112
is provided with a wire. The mounting element 160 is sleeved on the wire and
located in the
lower sealing element 220, the sealing sleeve 170 is sleeved on the lower
sealing element 220.
Optionally, as shown in FIG. 15 and FIG. 17, the lower sealing element 220 is
provided with a
mounting groove 222, the sealing sleeve 170 is sleeved in the mounting groove
222. The
mounting element 160, the lower sealing element 220 and the sealing sleeve 170
cooperate to
enable the lower sealing element 220 to tightly abut against the housing 240
to seal the liquid
storing cavity 260, so that the atomizing medium in the liquid storing cavity
260 only contacts
the liquid-absorbing surface 119 of the guiding portion 112. In this
embodiment, the lower
sealing element 220 is sleeved on the mounting element 160, the sealing sleeve
170 is sleeved
in the lower sealing element 220.
[0076] In one of the embodiments, the communication of the channels is shown
in FIG. 15, the
air channel 190 includes the first channel 191, the second channel 192 and the
main channel
Date Recue/Date Received 2022-12-15
193. Both the first channel 191 and the second channel 192 are in fluid
communication with
the main air channel 193 for the aerosol to flow out. Further, a gap is
provided between the
ventilation tube 150 and the atomizing portion 111 through the top portion 117
and the limiting
step 118, so that the second air channel 192 is in fluid communication with
the main air channel
193 through the gap. That is, a diameter of the ventilation tube 150 and a
diameter of atomizing
portion 111 can be the same or different, and the ventilation tube 150 and the
atomizing portion
111 are not in contact, so that a space communicating with the second air
channel 192 is formed
between the ventilation tube 150 and the atomizing portion 111. The space can
be used as a
part of the main channel 193, that is, the main channel 193 is in
communication with the second
air channel 192. In this way, two atomizing surfaces, the first air channel
191, and the second
air channel 192 are formed on the inner wall and the outer wall of the
atomizing portion 111,
so that a large amount of atomized aerosol can be obtained.
[0077] Further, as shown in FIG. 15, one end of the ventilation tube 150 abuts
against the
limiting step 118 through the middle sealing element 130 and an upper end of
the guiding
portion 112. The limiting step 118 cooperates with the ventilation tube 150 to
retain the fluid
communication between the first air channel 191 and the second air channel
192. The above-
mentioned structure effectively prevents the atomizing medium in the liquid
storing cavity 260
from entering the atomizing portion 111 from a position other than the liquid-
absorbing surface
119 through the middle sealing element 130 and its connection relationship,
and also prevents
the atomizing medium from being mixed into the ventilation tube 150 and the
main air channel
193.
[0078] Further, as shown in FIG. 15, the ventilation tube 150 passes through
the middle sealing
element 130 to enable the main air passage 193 to be in communication with the
first air
passage 191 and the second air passage 192. On the one hand, the bottom of the
atomizing core
assembly 110 abuts against the mounting element 160 and the lower sealing
element 220, and
abuts against the sealing sleeve 170 and the housing 240 through the lower
sealing element
220. On the other hand, the outer wall of the guiding portion 112 abuts
against the lower sealing
element 220, and abuts against the housing 240 through the lower sealing
element 220, so that
the housing 240 tightly abuts against the lower sealing element 220 and the
atomizing core
assembly 110, and the wire of the guiding portion 112 is sealed and isolated
from the liquid
storing cavity 260, so that the end of the liquid storing cavity 260 is
effectively sealed. In this
embodiment, the main air channel 193 is in fluid communication with the first
air channel 191,
16
Date Recue/Date Received 2022-12-15
and the main air channel 193 is in fluid communication with the second air
channel 192.
[0079] The sealing of the liquid storing cavity 260 is important. Since the
ventilation tube 150
extends through the liquid storing cavity 260, it is necessary to seal the two
ends of the housing
240 and the liquid storage chamber 260. In this embodiment, on the one hand,
the middle
sealing element 130, the ventilation tube 150 and the atomizing core assembly
110 fit tightly
to prevent the atomizing medium in the liquid storing cavity 260 from leaking
into the first air
channel 191 and the second air channel 192 though the gap between the
ventilation tube 150
and the middle sealing element 130. On the other hand, the lower sealing
element 220
cooperates with the sealing sleeve 170 and the mounting element 160 to apply
pressure to an
end of the housing 240, so that it is tightly sleeved on the atomizing core
assembly 110. A
sealing system is formed as a whole, so as to prevent the atomizing medium in
the liquid storing
cavity 260 from leaking out of the atomizer or into a position of the wire of
the guiding portion
112 through the gap between the mounting element 160, the sealing sleeve 170
and the housing
240. Such configuration achieves an effective seal for the housing 240 and one
end of the liquid
storing cavity 260.
[0080] In one of the embodiments, as shown in FIG. 16, the housing 240 is
provided with the

located on the upper
sealing element 210. The sealing pad 230 is provided with a second
communicating opening
231 corresponding to the first communicating opening 211. The main air channel
193 is
sequentially in communication with the first communication portion 211 and the
second
communication portion 231 to transport the aerosol, or the main air channel
193 is sequentially
in communication with the first communicating opening 211, the second
communicating
opening 231 and the nozzle structure 300 to transport the aerosol.
[0081] Further, in one of the embodiments, the upper sealing element 210 is
further provided

injecting holes 212
and/or each of the second liquid injecting holes 232, and only sequentially
communicates with
the second communicating openings 231, the first communicating opening 211 and
the main
air channel 193 through the flowing opening 301.
